#1. Triple H
This addition to the list is purely from a backstage perspective, not particularly related to the Triple H character. However, fans have been yearning for years for Triple H to eventually take the reins of WWE from Vince McMahon.
The reason behind such trust is due to his massive success in NXT, creatively and otherwise. It's clear that he's the perfect successor to the throne and he's being built and prepared for it accordingly.
McMahon stepping down will benefit Triple H more than anyone in WWE, because he finally won't be butting heads with his father-in-law over creative decisions and otherwise. We know for a fact that when Triple H eventually takes over, things are going to change big time from a creative perspective.
Hopefully, Triple H is able to handle the monster that is the main roster and thrive under the pressure of running professional wrestling's biggest juggernaut.
